[jdk21u] RFR: 8348760: RadioButton is not shown if JRadioButtonMenuItem is rendered with ImageIcon in WindowsLookAndFeel

Tue Sep 2 19:31:54 UTC 2025

I backport this for parity with 21.0.9-oracle

src/java.desktop/share/classes/com/sun/java/swing/SwingUtilities3.java
Resolved imports.

Resolved two more Copyrights.

With some luck this is clean.

Test requires follow-up 8365375.
